Cut size is part of the cooking plan
The idea
A recipe's cut size affects more than the appearance of the ingredients. It changes the surface available for seasoning and how you experience the center of a piece. Within one batch, very different sizes can also make it harder to judge when the whole batch has reached the texture you want.
A practical next step
Choose a consistent cut for an experiment at home. Change the seasoning in a later batch rather than changing every variable at once.
